SPEGEFGEQE' forming'part of Letters Patent No. 751,840, dated February 9, 1904. Application filed April d, 19035 Serial No. v151,107. (Eo model.)

To @Z5 whom it :carey concern/b n Be it known that i, GUs'rAv EHRHARDT, engineer, a citizen of the United States of America, residing at Eisenach, in the Grand Duchy of Saxe-Weimar and German Empire, have invented certain new and useful improvements in or leiating to Gun Carriages or Mountings, of which the following is `a specification.

My invention reiates to a gun-carriage or mountings for guns with tube-recoil, which diders from old gun-carriages in that the gun is guided by means of its protective or armor bars in the rings oi the pivot and of the elevator-slide holding the carriage.

The carriage is iilustrated in the accompanying drawings. in which'- Figure l shows| the carriage and gun in side elevation. Fig. 2 shows a guide-bar in section and in side elevation. section on line of Fig. l; Fig. 4, a crossseotion on line y y of Fig. l; Fig. 5, a crosssection on line ze of Fig. 1; and Fig. 6, a plan of Fig. l.

' The carriage a is surrounded by an extension b of the pivot having the form of a wide ring and by" a similar extension of the elevator.

device c. At the tcp the ring is provided on both sides with parallel parts d, forming guides. These guides engage with correspondl ing projecting angle-plates e-on lateral pro-A tecting or armor plates f, secured to the gun g and extending along the whole of its length.

vIn the carriage-tube a is arranged in the usual manner a brake-cylinder la, and as it has to follow the 'movements of the tube its rear end is secured to an extensionv z', arranged at the breech end of the gun g. At the muzzle end and over the pivot rings j or reinforcements surround the gun, without, however, being connected to the gun-carriage. Ledges 7c on each ringjserve for securing the armor-plates. They could, however, be secured direct to the Fig. 3 is a cross' .elevator-slide said rings being provided with Y gun, it .being only. necessary tothiclren it so as to have the same width in front'as at the back, as the plates f must be parallel. At the back or breech end the piates yare secured directly to the gun g. l

ln .order to protect sliding surfaces at the top, the parallel plates are provided with angular projections Z, vfitted 'to the shape of the gun, which is tapered.

The plates f, made of,l suitable material, form at -the same time an armor or protection for the sliding parts, and as the recoil is of such extent that both guiding parts don the rings never become uncovered the sliding parts cannot be injured.

Having now particularly described and ascertained the nature of my saidA invention and in what manner the same isv to be performed,

'I declare that what ,l claim is- 1. A gun carriage or mounting having a pivoted tube adapted to contain part of the recoil mechanism, said tubebeing provided with surrounding rings above the pivot and guides in which the movable gun is guided by means of corresponding guide-plates on lateral plates secured to the sides' of the gun or reinforcements,thereon,substantiallyas described.

i2. L The" combination of` a gun., armor-plates @on said gun, said armor-plates having internal protectedguide-rails, and a gun-carriage hav= ing members cooperating with said protected guide-rails, said members being covered always and protected by said guide-rails.

ln testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.

GUSTAV EHRHARDT.
